## What it is
logzero is a Python library that provides a fully configured, easy-to-use logger for Python 2 and 3, with colored console output, rotating logfile support, and optional JSON logging. It is contained in a single file with no required dependencies and is MIT licensed.

## Use cases
- add simple colored logging to a python script
- log to a rotating logfile in python
- output logs as  in python
- share one logfile across multiple python processes
- replace boilerplate python logging configuration

## When to choose
- you want zero-config, pretty logging in a Python 2 or 3 project
- you need console colors plus rotating file logging with minimal setup
- you want optional JSON-formatted logs without extra wiring

## When to avoid
- you need structured logging features beyond what logzero offers (e.g. distributed tracing)
- your project requires actively maintained dependencies with recent releases
- you are not using Python

## Facets
- artifact type: library
- maturity: maintenance
- function: logging, serialization
- domain: developer-tools, backend
- platform: python, cross-platform, windows
- tags: python-logging, -logging, rotating-logfiles, colored-console-output, zero-dependency, command-line, linux, macos
